Electromagnetic forming (EM forming or magneforming) is a type of high-velocity, cold forming process for electrically conductive metals, most commonly copper and aluminium. The workpiece is reshaped by high-intensity pulsed magnetic fields that induce a current in the workpiece and a corresponding repulsive magnetic field, rapidly repelling ...
Magnetic pulse welding (MPW) is a solid state welding process that uses magnetic forces to weld two workpieces together. The welding mechanism is most similar to that of explosion welding . [ 1 ] Magnetic pulse welding started [ clarification needed ] in the early 1970s, when the automotive industry began to use solid state welding.
An electromagnetic pulse (EMP), also referred to as a transient electromagnetic disturbance (TED), is a brief burst of electromagnetic energy. The origin of an EMP can be natural or artificial, and can occur as an electromagnetic field, as an electric field, as a magnetic field, or as a conducted electric current.
A pulse-forming network for an Nd:YAG laser rangefinder The Shiva Star device at Air Force Research Laboratory, USA, which generates pulsed power for high-energy fusion power experiments. Each of the 6 radial arms is a pulse-forming line delivering a pulse of energy to the center, whose capacitors store a total of 10 MJ of energy and can create ...
Energy is typically stored as electric potential energy within capacitors, or in the case of explosive pulsed power, as chemical energy.The stored energy is released over a very short time scale resulting in a large amount of power being delivered to a load which can be used to study high energy density physics phenomena such as Inertial confinement fusion using a Z-pinch, and plasma physics ...
Pulsed magnetic therapy, pulse magnetotherapy (PEMF) [ edit on Wikidata ] Pulsed electromagnetic field therapy ( PEMFT , or PEMF therapy ), also known as low field magnetic stimulation ( LFMS ) is the use of electromagnetic fields in an attempt to heal non-union fractures and depression . [ 1 ]
The magnetic flux threading the ring, represented by five field lines, is reduced by the same ratio as the area of the ring. The variation of the magnetic flux induces a current (red arrows) in the ring by Faraday's law of induction, which in turn creates a new magnetic field circling the wire (green arrows) by Ampere's circuital law. The new ...
The magnetic pulse welding process was successful in producing welds within advanced stainless steel fuel pin rods for the Fast Flux Test Facility reactor. He later represented Westinghouse Hanford taking the magnetic pulse welding process to Japan, his last great accomplishment before retiring.
